Patent CA-2760081-A1 (CA)
Inventor: LIU SHANGQING
IPC: G11B7/004
Filed: 2011-11-28
Abstract: This invention relates to the method of optical multi-dimensional data storage and the apparatus based on this method. More particularly, this invention relates to a six-dimensional optical storage method using multiple beams with different wavelengths, encoded intensities and polarizations to create each group of multiple wavelength selective, reflectivity specified and polarization sensitive tiny plane or quasi-plane Bragg reflectors in a small volume crossing through multiple storage medium layers as each storage cell. The maximum storage capacity of the apparatus based on this method can reach 10 Tbytes per disk or even more with fast data write, read and erase speeds. In addition, the apparatus based on this method has no interlayer noise and disk rotation caused data recoding and reading quality loss, and has good compatibility with existing CD and DVD drives.
